Solution Overview
Problem
Existing projection systems face issues with light leakage when optical fibers are disconnected from light source modules, posing safety hazards.
Innovation Solution
An optical fiber mounting mechanism with a mounting structure that includes signal contacts, magnetic elements, and locking elements, ensuring the power switch is turned off before complete disconnection by maintaining a greater depth of the receiving chamber than the effective contact or sensing distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the optical fiber is disconnected from the light source module for maintenance or replacement, then the optical fiber can be replaced or maintained, but light leakage occurs and causes safety hazards
Solution Approach 1:
The patent applies preliminary action by designing a mounting structure where the power switch is automatically turned off before the optical fiber is completely removed. The receiving chamber depth is greater than the effective contact distance, ensuring that electrical contact is lost first, triggering the power switch to turn off, before the optical fiber disconnects completely. This prevents light leakage during the replacement process.
2Reliability
If the receiving chamber depth is increased to ensure complete disconnection before power off, then light leakage is prevented, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into the mounting structure: mechanical retention of the optical fiber, electrical contact establishment, and power switch control. The receiving chamber serves both as a mechanical holder and as a means to control the sequence of disconnection, eliminating the need for separate sensors or control mechanisms.
Solution Approach 2:
The mounting structure is designed to automatically control the power switch based on the physical position of the optical fiber. The system self-regulates by using the depth of the receiving chamber to ensure electrical contact is lost before optical fiber disconnection, without requiring external monitoring or control systems.
3Productivity
If the effective contact distance is reduced to allow faster disconnection, then replacement speed increases, but the risk of light leakage during disconnection increases
Solution Approach 1:
The patent ensures that the power switch turns off in advance before the optical fiber is completely disconnected. By designing the receiving chamber depth to be greater than the effective contact distance, the system guarantees that electrical contact is lost first, triggering the power switch to turn off, before the optical fiber disconnects, thus preventing light leakage regardless of disconnection speed.
